Challenge a suspicious caller while they are still on screen.
Send a one-time link during the video call. The person completes a randomized response on their phone, then you review the timestamped evidence once before the images are deleted.
CallCheck is a human-reviewed spot check. It does not claim to identify every synthetic caller or replace formal identity and KYC controls.
